I have 20 X 8.5 +35 Offset Front and 20 X 10 +40 Offset Rear
The fit was pretty good IMO. Front tires re flush and the rear stick out a smidge. The only complaint that I have after going from 19" wheels to 20" wheels is the ride quality has dropped a little. Lowered car plus short tire height will make you feel every bump.
I have pics on this thread:
